Question

perimeter of a rectangular sheet is 100 cm if the length is 35 cm find its breadth also find the area ​

Answer 1

Step-by-step explanation:

perimeter=100 cm

length=35 cm

breadth=?

peeimeter=2(l+b)

100 =2(35+b)

100 =70+2b

100 -70=2b

2b=30

b= 15

so,breadth is 15 cm.

now,

area=l×b

( 35×15)sq.cm

525sq.cm

Therefore breadth=15cm and area=525sq.cm.

Answer 2

Answer

Perimeter of rectangular sheet

☞︎︎︎ 2(l+b)

☞︎︎︎ (35+b) = 100÷2

☞︎︎︎ (35+b) = 50

☞︎︎︎ b = 50- 35

☞︎︎︎ b = 15

Area of rectangular sheet

☞︎︎︎ l×b = 15×35 = 525 sq cm.
